I have found that sulfur & copper sulfide do pull out zinc but they also pull out tin .
I prefer using copper sulfide (root killer) because it adds a little copper to the melt which makes the boolits more elastomeric

I shot 99% Pb 1% Zn in 40sw, no problem, they even looked good. Sulfur is a hardener, slight to Pb but much better with some Sb. Sulfur will take Cu & Sn out of alloy. Works similar to As.
Whatever!
I believe you are referring to copper SULFATE, CuSO4(H2O)x, where x can range from 0 to 5.........a root killer readily available in the plumbing departments of any hardware and big box store. It definitely removes Zn, is relatively safe, and does not create clouds of toxic smoke and fumes. I have used it in the past to successfully remove Zn ( and Sb and Sn also!) from an alloy. You end up with almost pure Pb.
It's blue color is from the H2O locked in it and as it cooks, it will turn it's natural white.
Best way to remove Zn from your mix is to take necessary steps to NOT GET IT in there in the 1st place. But as I stated above, up to 5% will hurt nothing.
